My HP laptop will not play any dvd movies. It will do just fine on data dvds and blank dvd's but dvd movies, the drive just grinds away and tells me to insert a disc when there is one in it. I downloaded the most recent codecs for media player. Installed cyberlink power dvd, installed vlc, all with no avail. I didn't think any of those would work since the drive does not even recognize there is a disc in it to play, it just grinds away. Is the only solution a new drive? It plays audio cd's just fine also. I tried the Microsoft fixit and the registry entries on filters, etc. Still does not work.
